I am running a DB Tuning Expert program. The program informs me that my DB_BLOCK_BUFFERS is below 90 %. I edited the init.ora file and increased the DB_BLOCk_BUFFERS. Now I am getting a different message. The message is " Too high ratio of average number of blocks scanned by the DBWR (database writer)-2570.0 as compared to all scans on the LRW chain. DBRW is working to hard"

Does anyone know how to resolve the above problem.

Thanks in advance
